I would question the statement that CCDs were first designed
specifically for cameras. Wasn't the analog delay line the first use
of CCDs? The linear array CCD came along before the 2D matrix.

Exactly my own recollection, Don.

What I did find interesting was the different emphasis being put on the
reasons behind using CMOS - not because it provides a higher image
quality, but because it makes for a cheaper system, and that the quality
has only recently become "acceptable" for small sensors.

Maybe they realize a policy of honesty will draw more support.

But it could be the case. For one thing, "designed/developed" and
"commercially
available as a product" also are different things. :-)

Back in the days of CCD's as analog delay lines (for low cost consumer
applications)
I know they were built (2" wafers I think, but could have been 1") for
camera applications
for telescopes by Tektronix (probably as part of Teklabs, in obviously
small quantities).
More of a research project (Teklabs back then was much like Bell Labs
where they did
pure research just for the pure science of it, not product related).

So I don't know it to be true, but CCD's as camera devices could very
well have happened
before analog delay line applications -- at least in the lab that made
them originally.
